Specification of Letters Patent.

Application filed March 6, 1917. Serial No. 152,570.

To all whom it may concern:

Be it known that I, JOSEPH RAUWALD, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Safes and I do hereby declare that the following is a full, clear, and exact description thereof.

It is in general the object of the presentinventionto simplify and otherwise improve tie structure and to increase the eificiency and operation of devices of this character and more particularly with respect to the simultaneous movement of the inner and outer doors, it is an object to provide an arrangement wherein such movement may be procured in an exceedingly positive and easily actuated manner.

A further object resides in the provision of a means for locking the outer doors together which is operable incidental to the opening movement of the doors, by the application of the usual actuating key.

With the above and other objects and advantages in view, the invention resides more particularly in the novel combination, formation and arrangement of parts hereinafter described and particularly pointed out in the appended claims. I

In the drawings:

Figure '1 is a horizontal sectional viewv through the. safebetween the top walls of the inner and outer casings, the plane of this iection being indicated by the line 11 of Fig. 2 is a horizontal sectional view between the bottom walls of the casings looking upwardly, as indicated by the line 2-2 of Fig. 3.

Fig. 3' is a vertical sectional view through the safe on the line'33 of Figs. 1 and 2, the lower portion of this view being cut in a plane inwardly of the upper portion.

Fig. 4: is a vertical transverse sectional View through the safe on line 4-}1 of Fig. 2, looking-outwardly.

Referring by numerals to the drawings, 5 indicates a cast-metal frame constituting the front of an outer all-metal casing, and the frame is provided with rearwardly extending jamb-flanges 6 ofi'set inwardly.

Top, bottom and side wall plates 7, 8 and 9 respectively are secured to and extend rearwardly from the peripheral edges of the frame 5 and terminate at a rear wall 10. I

Within the outer casing is a chamber comprising cast-metal top and bottom plates 11 and 12 respectively, and a sheet-metal shell .13 comprising the side and rear walls of the chamber, the plates and chamber being secured together by screws 14 passed through projected ears of the plates and engaged in holding rods 15. The rear portions of the plates and top and bottom walls are braced and secured together by screws 16 passed through the walls 7 and 8 and engaged in bosses 17 projecting outwardly from the plates. The walls of the chamber and of the casing are spaced apart throughout and thus an air space surrounds the entire chamber.

The forward portions of the plates 11 and 12 are secured to corresponding top and bottom outer casing Walls 7 and 8 by bosses 18 projecting outwardly from the plates and connected with the said walls and these bosses serve also as the pivots for upper and lower pairs of crank arms 19 and 20 respectively, which carry at their outer ends a pair ber plate 11 and also between the upper head 23 and a plate 24 on the upper boss 18 are disposed annular series of ball-bearings 25 surrounded by suitable retaining rings 26. The plate 24 is secured on the boss 18 by a screw 27 passed therethrough and threaded in the boss, and the securement of the outer top wall 7 to the boss comprises a screw 28 passed through saidtwall and threaded mto the boss carried screw 27. The inner ends of the crank-arms 20 comprise bearing heads 29 on the lower boss 18 and between these heads and the inner chamber wall 12 and a plate 30, similar to the plate 24 are disposed ball-bearings 31, retained by rings 32, the plate 30 and the bottom outer casing wall 8 being secured by screws 33 and 34, similar to the screws 27 and 28. At the inner sides of the heads 29 are formed arcuate series of gear teeth 35 meshing with a preferably beveled gear pinion 36 carried on a shaft 37 having one end journaled in the lower boss 18 whereby upon rotative' movement of the shaft in either direction, the doors 21 will be opened or closed.

For simultaneously rotating this shaft, and actuating a locking means for the doors, a lock casing 38 is carried at the lower central portion of the outer casing frame 5 by securement to said casing and to a depend-- ent car 39 at the front of the lower chamber 4 plate 12 and rotatively mounted in this casing is a spindle 40 recessed at its outer end to receive a suitably longitudinally grooved key 41. The head of this key being provided with pins 42 adapted to engage in the spindle, whereby upon rotative movement of the spindle by the key, the shank of said key will be relieved from strain. The inner end of the spindle rotatively seats in the enlarged socketed end 43 of the gearshaft 37 and is limited in its movement with respect thereto by means of a lateral lug 44 projecting through a slot 45 in the sleeve.

The limited freedom of movement of the spindle with respect to the sleeve 43 serves to release or actuate a suitable door locking means, a continued movement of the spindle turns the shaft to open or close the doors.

This locking means for the doors comprises a lever 46 pivoted at one end to one of the doors 21 adjacent its inner edge, and having its other end adapted' to project through slots 47 in the door flanges 22 and upwardly extending in hook shape whereby when said end is raised the doors are locked together. To the intermediate portion of the lever is pivoted a locking bar 48 slidable through guide lugs 49 on the "inner face of the door and having a rounded head at its upper end slotted to receive a depending lug 50 on the upper chamber plate 11. The le- .ver is normally urged to its raised locking position by a spring 51 and carries pad blocks 52 engageable with the guide lugs 49.

' The locking bar 48 is extended downwardly insertion of the key in the 21 and locking means,

below the plate 12 at its forward edge and terminates in an inwardly extended finger 56 engageable by the lug 44 of the lock spindle.

Taking up now the operation of the doors it is seen. that when the doors are closed and looked that upon lock spindle and 'of the slot 45 and continued movementof the spindle will rotate the shaft 37 to swing the doors open. As the doors move apart,- the finger 56 of the bar 48 moves outwardly of the bifurcations of the lug and the looking bar is raised by the spring 51. In closing movement of the door, the' upper head of the locking bar and the hook lever have a cam action with respect to the lug 50 and the slots 47 respectively.

The front of the inner chamber is closed by doors 57 which are provided at their lower ends with depending pintles 58 journaled in the bottom plate 12 and provided at their inner upper corners with pintles 59 journaled in the upper plate 11. At the upper edge of each door adjacent its pivotal axis is provided an upstanding pintle 6O slidable in an arcuate slot 61 in the plate 11.

Journaled on one of these pintles is a roller:

62 and the other of said pintles has secured thereto one end of a bar 63 which has its intermediate portion secured to the projected end of the adjacent pivot pintle 59 and which is extended rearwardly of said pintle for securement to one end of a link 64 which is secured at its other end to the roller carrying pintle 62. Secured to one of the upper outer door crank-arms 19 is a forwardly projecting cam-block 65 adapted to engage the roller 62 to swing the inner doors to closing position, and extending from this cam-block under the arm 19 is a retaining wall 66 against which the roller 62 abuts to positively lock the inner doors in closed position when the outer doors are closed or partially closed. Opening movement of the inner doors is effected by abutment of one of the flanges 22 ofthe outer doors with a lateral wing 67 at the inner end of the cor-- responding inner door.

What is claimed is:

1. A structure of the class described including a casing, a door for closing the easing, means for locking said door, means for moving said door including members having limited relative movement, and means connecting one of said members and the locking means for releasing said locking means upon relative movement of the said 'member with'respect to the other member.
